To the accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawings and the followingdescription setting forth in detail certain mechanism embodying theinvention, such disclosed means constituting, however, but one ofvariousmechanical forms in which the principle of the invention may beused.

In said annexed drawings Fig. 1 shows in side elevation a vacuum cleanerof a common type embodying the principles of this invention; Fig. 2 is afront elevational view of a suction nozzle showing a floor tool attachedthereto; Fig. 3 is a vertical sectional view along the lines 3-3, Fig.2; Fig. 4 is a fragmentary bottom view of Fig. 2 and Fig. 5 is anisometric pr.o]ecti0n of the spring clamp used in attaching the floortool to the suction nozzle.

Referring more specifically to the drawings and especially Fig. 1, thevacuum cleaner here shown is of the usual type having a motor element 1,an air filtering and dust collecting element 2, suction chamber 3,tubular handle 4, and suction nozzle 5. The suction nozzle:

5 shown more specifically in Fig. 2 has supporting wheels 6 securedthereto by means of wheel mountings 7 and 8, said wheel mountings beingmore fully described in my coending application filed February 27 1929rial No. 342,979. Attached to the front 0 said-suction nozzle 5 is afloor tool 9, said floor tool being composed of a flexible element 10and a brush securing element 11. Sad flexible element 10, which isusually felt or other they secure may-be attached to such nozzle .ed estot and are secured in the retaining position shown in Fig. any. meansof; a plurality of bolts 13 extending therethroughand securedby nuts 14.The securing bolts 13 adjacent to thevendfofsaid floor .tool also securethe spr ng clip members 15 tosaid floor tool. The spr ng clipmember 15has an. aperture16 formed therein,-;,for engagement with the securingbolt 13, and bein secured to thefloor tool by means of this bo t alone,is permitted to rotate about said retaining bolt 13. Ito-- tationof'thespring clip member 15.with respect to the floor tool permits the floortool to be attached to the suction noz'zlewith eitherthe brush, or theflexible edge in .the. .downward, direction. I The-spring clip15 has itslower end l7 bent in'a substantially U-shape to present an engagingmeansfor thes ring: clipin the, aperture 1 8 formed therefor 1n the lowerface of the suction nozzle as most clear- 1y shown in Fig. 4.Adjacenttheupper end of the springlclip 15, an aperture19 isformed toengage t e boss 20-on the upper. face of the suction': nozzle 5.. lThe.boss v20.fo'r retaining the spring clip in operative position ispreerably-hemispherical inform and of greater diameter than the aperture19 formed therefor in the-springiclip 15, j r The diameter of said-boss-20zbeing greater. than the di-- ameter of said aperturef'19'prevents the spring clip, from coming-in contact withthe polishedsurface :of the "suction nozzle 5,

thereby preventing the polished surface ;from becoming marred when suchspring cli is attached and detached from such nozzle. he boss '20-may'preferablybe the head of the screw employed'in this type of nozzleto securethe wheel mountings 7 and 8 in the sockets formed'therefornozzle5;

,; It will .be :seen that a floor tool may be attached to -*a-,..suctionnozzle by-means of a" spring clip .withoutin any way marring the highlypo ished surface which is'common to such suction nozzles. Also, bya mererota-" tion" of the spring clips, the'floor tool which so as to plresenteither of its longitudinal-- in the end of suction e surface to beeither cleaned' j it I Other, modes of applying the principle of myinvention may be employed instead of the one explained, change beingmade as regards the mechanism herein disclosed, provided the meansstated by any of the following claims or thedequivalent of such statedmeans be emp therefore particularly point out and distinctl claim as myinvention 1. he combination with a suction nozzle, of a floor tool, areversible clip for attaching said floor tool to said nozzle including amember to engage the nozzle from below, an aperture formed near one endof said clip, and a boss on the upper side of said nozzle to secure saidclip, said boss having a reduced upper end to engage said aperture insaid clip and secure it out of engagement with the surface of thenozzle.

2. The combination with a suction nozzle, of a floor tool, a reversibleclip attached to said floor tool for securing said tool to said nozzle,an aperture formed near one end of said clip, a recess in the lower faceof said nozzle adapted to receive the other end of said clip, and a bosson the upper surface of said nozzle, said boss being hemispherical inshape'and of a larger diameter than the aperture in said clip.

13. In combination with a suction nozzle provided with a boss on itsupper surface, a floor tool, a clip attached to said floor tool forsecuring said tool to said nozzle including a lower member to engagesaid nozzle from below and an upper member formed to receive a portiononly of said boss whereby the clip will be supported by the bossout ofcontact with the upper surface of the nozzle.

4. In combination with a suction nozzle provided with a hemisphericalboss on its upper surface, a floor tool, a clip attached to said floortool for securing said tool to said nozzle including a lower member toengage said nozzle from below and an upper member formed to receive aportion only of said boss whereby the clip will be supported by the bossout of contact with the upper surface of the nozzle.

5. In combination with a suction nozzle provided with a boss on itsupper suface, a floor tool, a clip attached to said floor tool forsecuring said tool to said nozzle including a lower member to engagesaid nozzle from below and an upper member formed to receive a portiononly of said boss whereby the clip will be supported by the boss out ofcontact with the upper surface of the nozzle, said clip having at itsopposite end a hook, and a recess in the lower face of said nozzleadapted to receive said hook.

6. In combination with a suction nozzle provided with a boss on itsupper surface. a floor tool, a clip securing said floor tool to thenozzle, including a lower member engaging the nozzle from below,anintermediate porermost portion said lowermost portion being formed toreceive said boss.
